摘要

The crack propagation path of oriented perforation hydraulic fracture is studied using the fast multipole dual boundary element method (FM-DBEM). The method demonstrates high accuracy and computational efficiency, as validated by close agreement between computed stress intensity factors and theoretical solutions as well as published numerical benchmarks, confirming its applicability and robustness. These findings establish the FM-DBEM as a powerful and efficient numerical tool for capturing the coupled effects of geological parameters, operational conditions, and fracture interactions in hydraulic fracturing. The results provide a solid foundation for optimizing perforation design, injection strategies, and cluster spacing, ultimately contributing to more effective and reliable reservoir stimulation.
